I was kind of curious about that myself, so I re-ran it with no spec
file. Here's its ps output:
PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command
9704 reid 20 0 1724M 892 704 S 0.0 0.0 0:00.00 ./algencan
That 1724M looks a little scary. (I have 4 GB here.)
I don't speak fortran too well, but the code does seem to allocate
some decently hefty amounts of memory, such as this:
double precision nl(nmax),c(mmax),rho(mmax)
where mmax is 500000. There must be others, too. Maybe you don't
want to run this thing on your low memory machine...!
